Which of these statements is true regarding the way light travels?
A. Sound travels faster than light.
B. The speed of light is always the same regardless of the medium through which it
travels.
C. Light travels as both a wave and a particle.
D. Light can not travel through a vacuum. - ANSWER C. Light travels as both a wave
and a particle.
Light is a curiosity in that it acts as both a wave and a particle. It only changes direction
via reflection (bouncing off of something) or refraction (passing from one medium to
another). In a vacuum, the speed of light is constant, but when passing through a
medium that has an index of refraction different from a vacuum, light's speed slows.

, What is the only artery in the body to carry oxygen-poor blood?
A. renal artery

Most arteries in the body carry oxygen-rich blood away from the heart, but the

the question asks for an artery.

Endometriosis is a condition in which the tissue from the uterus (endometrium) grows in

brown, hence the term "chocolate cyst."
